The lime plastering on exterior walls was made using local sand sourced from site excavations. It brings a natural effect to the house and makes it unique with the Arugal approach (low carbon footprint + geo-sourced materials). In terms of the Interior, the design is voluntary minimalist (to limit maintenance and make operation easy). Tailor-made cement tiles, loose furniture in solid wood, and plywood for false ceilings bring both a Vietnamese touch and coziness to the Villa. Lighting designed by Kobi Studio will be contrasted to preserve the darkness of the sky (and respect the rhythm of nature around) and only focus the light where it is necessary (reading corner, dining and kitchen areas, bathroom, and bedrooms).
